You might consider a "real" Welbourn foil that would be simpler and lighter . I imagine you have-or will- do the calculations to make sure the foil area you choose will work. The Quant 23 system designed by Hugh Welbourn also has the advantage of really light air takeoff. His Quant 23 was the first foiling keelboat ever....
Good Luck-sounds like fun.

revintage quote:
"A foil like that is out of the question due to the costs involved. My solution will do the same job. How do you think I found out the take off speeds without doing the math?
The lifting foil will be parallell to water surface at 16% heel.
Will use my straight foil section described in my Trifoiler thread. "
----------------------------
You think one "Gonet" type foil(foil+2 "legs") will cost less than one Welbourn foil? I seriously doubt it. Hope it works out.
What is your projected takeoff windspeed?

TANSL, it might be worth a try to use the original daggerboard(if it is long enough) in foiling mode, as the leeward foil ads righting moment by the lengthened righting arm. Have to do the math on that option.
